DELIVERING MECHANISM FOR. B'OLT-TRIMMINQ MACHINES Application led-Noveniber 13, 192.6. f Serial No. 148,289.

metal or flashing removed from the bolt travels therewith and it has been diflicult to separate this scrap metal from the bolts by the means heretofore employed.

It is an object of the present invention to provide simple and eflicient means for insuring separation of the scrap from the bolts so that the trimmed bolts will be directedv into a container provided therefor while the scrap will be delivered in another direction from the machine.

With the foregoing and other objectsA in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the det-ails of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed may be made within .the scope of what is claimed, ithout departing from the spirit of the invention. 1

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings, Figure 1 is a plan view of the delivery mechanism constituting the present` invention, its supporting structure being shown in horizontal section.

Figure 2 is an end elevation of said mechanism. v

Figure 3 is a section on line 3 3, Figure 2. Figure 4 is a section on line 4 4, Figure 3.

Figure 5 is an enlarged section von line 5 5,

Figure 3.

Referring to the figures by characters of reference 1 designates the frame work constituting the supporting structure of the delivery mechanism and supported in the lower portion of the frame work is a tray 2 having an outlet chute 3 at one side thereof while d elivering downwardly into this tray is a feed chute 4 suitably vsupported and projecting outwardly beyond the structure 1.

Journaled within the upper portion of the structure 1 is a transverse shaft 5 adapted to be driven through meshing gears 6 'and 7 from a shaft 8 likewise journaled in the structure 1 and which, in turn, can be actuated by a belt 9 mounted on a pulley 10. i

Shaft 5 isl provided with a sprocket 11 on which is mounted a chain conveyor 12 to certain of the links of which are attached blocks 13 having'pivot pins 14 or the like whereby the blocks are pivotally attached to their links. Each block has a longitudinalohannel 15 in its outer face and, as shown particularly in Figures 1 and 3 these channels register to provide an unbroken upper flight for the conveyor. the said flight having unbroken side flanges. Thus material being conveyed by the conveyor will be retained thereon until a point above the sprocket 11 is reached. Here the blocks 13 shift relative to each other so that the bolts 0r other articles carried by the v blocks will be carried over the sprockets and delivered downwardly by gravity into a separating trough 16. Y

The separating Vtrough is supported by the structurel between chute 4 and the upper portion of the conveyor'and said trough is inclined downwardly kso that articles delivered thereto vwill gravitate toward the lower end of the trough. The bottom of the trough,

indicated at 17, has its sides converging downwardly toward a longitudinal slot 18 open lat its ends. The lower end of the trough is braced transversely as indicated at 19 and at an intermediate point npstanding stri s 2O are fastened to the sides of the trouglgi. These strips are connected by a cross rod 21 and suspended from this rod are chains 22 forming'a flexible partition extending across the trough, the chains being of such length as to extend from the rod to those portions of the bottom of the trough directly under the points of attachment to the rod. This arrangement has been clearly illustrated in Figure 5. Flanges 23 extend downwardly from the sides of the slot 18. Y

Y In practice the trimmed bolts with the flashings or scrap metal mixed therewith are 'delivered from the channels l5 in the blocks 13 to the trough 16. The bolts will travel by gravity along the trough because they are too remaining with the bolts, thereby retarding" the same without, however', holding back the bolts. Consequently the scrap or {lashings will be separated from the bolts by the chains and gravitate through the slot'18 whilefthe bolts, gravitating from the trough 16, will be delivered past the upper end of the chute l into a suitable container provided for them.

l/Vhile in practice it has been found most convenient and desirable under many conditions to use suspended chains, it is to be understood that in lieu of these chains other. yielding means sueh as rods, plates and the like hung to swing freely, could be used equally as well as the chains.

What is claimed is: f

l. A separator for bolt trimming machines ineludingvan inclined longitudinally slotted trough, and a row of inert scrap retarding members within thel trough and having free lower ends for free swinging movement from pressure tliereagainst by moving bolts.

2. A separator for bolt trimming machines including an inclined longitudinally slotted trough, and a row of independently swing-y ing, inert scrap retarding members withiny the trough for free swinging movement Jfrom pressure thereagainst by moving bolts.

3. A se aarator for bolt trimming machines o i u n b including an inclined longitudinally slotted Vtrough and a row of independently swinging wiLnnii/i L. cLoUsE.
